From the previous record, the average length of semiconductor device of a certain factory is 162.5 millimetres with a standard deviation of 6.9 millimetres. If a random sample of 50 devices in a specific batch has an average length of 165.2 millimetres, can we claim that there has been a change in the average length of all the devices produced by the factory? Use a P-value approach for the hypothesis test.
